A comparative study of porosity, oxide contents, bond strength and wear resistance of 3Cr13 stainless steel coatings deposited by high velocity and regular arc spray processes was carried out. An orthogonal and rotational regression experimental method and an ordinary single-factor experimental method were adopted to evaluate the coating hardness with respect to the effect of processing parameters. The quantitative formula of processing parameters with coating hardness was obtained by means of microcomputer.

摘 要：对比研究了3Cr13不锈钢高速电弧喷涂涂层和普通电弧喷涂涂层的孔隙率、氧化物含量、涂层结合强度和滑动磨损性能，并采用多因素正交旋转回归设计和单因素对比试验的方法研究了高速电弧喷涂工艺参数对3Cr13不锈钢涂层显微硬度的影响，用微机回归得到了喷涂工艺参数与涂层硬度之间的定量关系式。

So it usually needs to roughen the surface toimprove the bonding strength. But the coarseness was not used in this paper. The technique ofarc spraying zinc in advance and then arc spraying copper was put forward to solve the problemof bonding strength.

而本研究根据锌喷涂层具有较好的附着性，提出了在电铸层上先喷涂锌后喷涂铜的工艺路线，较好地解决了铜喷涂层与电铸层结合强度偏低的问题。

There was an obvious phenomenon of mechanical occlusion on the cold spray coating interface, and the rolled coating had the phenomenon of metallurgical bonding; The structure of cold-sprayed coating is dense. The poriness of the cold-sprayed coating gradually reduce as the coating's thickness increase.

结果 涂层界面形貌的不同反映出两种涂层的结合机理不尽相同，冷喷涂层界面出现明显的机械咬合现象，而轧制涂层以冶金结合为主；冷喷涂层组织致密，孔隙率随着喷涂厚度的增加逐渐降低；冷喷涂层的表面粗糙度高于轧制覆铜板，有必要对其进行一道轧制处理，改善涂层表面平整度。

High-pressure airless spraying machine is divided into pneumatic airless paint sprayer, electric airless spraying machine and electric airless paint sprayer, because of Pneumatic Airless paint sprayer with compressed air source required while limiting the use of pneumatic paint sprayer.

高压无气喷涂机分为气动式无气喷涂机，电动式无气喷涂机和电动无气喷涂机，由于气动式无气喷涂机需要带压缩空气源而限制了气动喷涂机的使用。

The traditional arc spray gun can only spray same material, but the arc spraying and flame spraying can be synchronously completed by use of the new device.

基于针对电弧喷涂应用的局限性，设计了一种能有效结合电弧喷涂和火焰喷涂优点的复合式电弧喷涂枪。
